COMPOSTIE RAILROAD-TIE Application filed August 30, 1920.

To UJZ whom it may concern:

Be it known that 1, WILLIAM H. ELLIo'r'r, a citizen of the UnitedStates, residing at lVashington, in the District of Columbia, haveinvented new and useful Improvements in Composite Railroad-Ties, ofwhich the following is a specification. I

The object of my present invention s the provision of a simple anddurable railroad tie constructed with a view to taking up shock and jarand eliminating noise and also constructed with a View to facilitatingrepair-of the tie when occasion demands.

To the attainment of the foregoing the invention consists in theimprovement as hereinafter described and definitely claimed. in theaccompanying drawings, hereby tirade a part hereof i Figure l is a planview ofa portion of a railway embodying several ties constructed inaccordance with my invention.

2 is view partly in elevation and partly in section showing one of mynovel ties and the arrangement of the same in relation to the rails andmeans by which the rails are detachably connected to the tie.

Similar numerals of reference designate corresponding parts in bothviews of the drawings.

The rails 1 may be and preferably are of conventional construction.

My novel ties are identical in construction and therefore a detaileddescription of the tie shown in Fig. 2 and the appurtenances thereofwill suffice to impart a definite understanding of all. The tie referredto comprises a tie proper or body 2 of concrete or concrete reinforcedin appropriate manner with metal, cushioning elements 3 of wood on whichthe rails 1 are superimposed, bolts l with angular heads 5 at theirlower ends countersunk in the underside of the body 2, and nuts 6mounted on the upper threaded portions of the bolts to detachably holdthe cushioning elements 3 to the upper side of the body. The said tiealso comprises means to fasten the rails to the cushioning elements 3.This means includes a plurality of bolts 7 with angular heads 8countersunk Specification of Letters Patent.

Serial No. 406,839.

in the undersides of the cushioning elements 3, clips 9 mounted on theupper portions of the bolts 7 and adapted to rest over the bases of therails, and nuts 19 threaded on the upper portions of the bolts 7 andadapted to strongly hold the clips 9 down a ainst the upper sides of thewooden cushioning elements 3.

The simplicity of my novel tie construction will be readily appreciatedfrom the foregoing, and in the practical use of the tie it will beunderstood that the Wooden blocks or cushioning elements 3 serve toabsorb shock and jar and to prevent the imposition of the same on thetie body 2 so that there is no liability of the said tie body crumblingor breaking. It will also be apparent that the interposition of theelements 3 between the rails and the tie body 2 practically eliminatesnoise and contributes to the smooth passage of trains on the rails. Mynovel tie construction is also adapted to lend itself to facility ofrepa'r for it will be readily ap parent that by jacking up the rails andin- 'l:erposing new blocks 3 and bolting the rails down again, theusefulness of my novel tie construction may be indefinitely prolonged.In this connection the arrangement of all of the nuts at the upper sideof the improvement is of material advantage, as is also the arrangementof the angular bolt heads in the undersides of the tie body 2 and theblocks 3, respectively inasmuch as the bolts are thereby held againstturnin about their axes without the assistance 0 extraneous means.

Having described my invention, what I claim and desire to secure byLetters-Patent, is

A railroad tie construction consisting essentially of a tie body ofconcrete having angular countersinks in its underside, a cushioningblock of wood superimposed upon said body and having angular countersmksin its underside, bolts having angular heads arranged in saidcountersinks in the underside of the tie body, said bolts extendingupwardly through the tie body and the cushioning block and havingthreaded upper portions, nuts removably mounted on said and the clipsand having threaded upper threaded portions, clips mounted on the ends,and nuts mounted on said ends and discushioning block and adapted tohold a-i'u-il posed above the clips; the cushioning block 10 down uponthe same, bolts having lower 2111- and the rail being separable as aunit from 5 gulzu' heads arranged in the eountersinks in the concretebody.

the underside of the cushioning block said In testimony whereof I aflixmy signature. bolts extending upwardly through the block VILLIAM H.ELLIOTT.
